Both Teen Mom stars have published books since the show aired and BOTH works chronicle adult subject matter, like sex and drugs. Portwood believes kids should not be associated with grown-up topics in the media, while Abraham tweeted the following:

@F1abraham@MTV I did it out of respect for my 6 year old who shouldn't be on the cover of a book talking about drugs and sex..love not hate

Well, it's clear both moms feel strongly on the topic.

Fellow Teen MomKailyn Lowry even got in on the beef after a fan suggested Farrah was specifically calling out other members of the franchise because most of the moms who've published books do NOT have their kids on the covers.

Zayn previewed the duet by posting a black and white pic of himself with Swifty on his Instagram -- but hey, she is bestiez with his girlfriend Gigi Hadid, so it wouldn't be unusual that they hang out... But collab?!
